Suppose you're being asked to sign a legal document that you don't fully understand, consult an attorney before signing. Once you've signed the document, you are acknowledging your understanding, and you are committing yourself to everything contained therein. If the contract is unlawful, there may be a way out of the commitment, but that will be much more costly than amending the contract or getting clarification before signing. Our contract law attorney is Anthony O'Malley.
